Datasheet: IA3004-CE10A (Rohm)

The BP51L05 and BP51L12 are DC / DC converter units that use a pulse width modulation (PWM) system. They containbuilt-in control circuits, switching devices, rectifiers, and coils, and operate if only an I / O smoothing capacitor is con-nected. With a wide range of input voltage, the ICs are best suited for obtaining a stable local power source from a mainpower supply with a large voltage variation.

sults in increased rush current, and may cause damageto the hybrid IC and overshooting of output voltage.Check for this problem, which is dependent on the risetime of input power supply and load conditions, in the ac-tual application. As a guide, input power supply of 10msor greater is required against rush current, and 100ms orgreater against overshooting. Suppress the peak valueof rush current to 2A or less.

Pins 2 to 7 are ground pins that are connected to

each other internally. Not all pins have to be used.(4)

The IC contains no circuit to protect the output cur-

rent. If short circuit is feared, use the ICP or other protec-tion measures.
